Abstract

P-dibromobenzene nanoparticles in a case of paradihlorbenzol molecules have been synthesized. Raman spectrums of these nanoparticles are measured. At diffusion of molecules of paradihlorbenzol in a pdibromobenzene nanoparticle solid solution formed. Modifications in structure of nanoparticles at diffusion are reflected in Raman spectrums. Unlike a solid solution single crystal, in nanoparticles the accelerated diffusion, D = 1.3 ± 0.02 10^-11 cm²/s, is observed at room temperature. Calculations show that the accelerated diffusion is caused by magnification of parametres of a lattice at reduction of sizes of nanoparticles.
